The Muslim Brotherhood has called for a mass demonstration in Cairo and other governorates on Tuesday to support President Mohamed Morsy’s controversial constitutional declaration.

The protest call could potentially cause further political fallout and civil unrest, as secular and liberal parties opposing the declaration have also called for protests Tuesday.

But In a statement published on its website, the Brotherhood said that they will mainly gather in Cairo’s Abdeen Square, not in Tahrir Square, which continues to be the scene of anti-Morsy protests.

Morsi's declaration — which acts as a temporary charter — allows him to issue any law or decree "to protect the revolution" that toppled Hosni Mubarak last year, with no decision or law subject to challenge in court.

Protesters torched Muslim Brotherhood offices on Friday, state media said, as supporters and opponents of Morsy continued to stage rival rallies across Egypt two days after he issued the declaration.
